The Rocket Attack Hyper Shot finish 1-piece semi-forged wheel was purpose built to deliver track purpose style and performance for the finest muscle cars, pro-touring and street machines at very affordable prices. The Rocket Attack features a cast center that can be moved within a wide range of offsets inside the spun forged outer, providing options that until now were available only from expensive multi-piece wheels. This breakthrough technology delivers weight and metal strength characteristics comparable to high-dollar forged wheels. Every Attack series wheel has undergone rigorous SAE J2530 automotive aftermarket testing for street performance.
